ObjectiveTo observe the clinical effect of modified Huanglian Wendantang on cardiovascular risk factors in patients with metabolic syndrome under the guidance of treating disease before its onset. MethodsA total of 82 patients with metabolic syndrome treated in the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from July 2023 to July 2024 were selected and allocated into an observation group （41 cases） and a control group （41 cases） by the random number table method. The control group received routine treatment， and the observation group was treated with modified Huanglian Wendantang on the basis of routine treatment. Both groups were treated for 8 weeks. The therapeutic effects on TCM symptoms after treatment in the two groups were evaluated. The levels of obesity degree indicators， blood pressure indicators， glucose and lipid metabolism indicators， inflammatory factors， and vascular endothelial function indicators before and after treatment in the two groups were measured， and the treatment safety was evaluated. ResultsAfter treatment， the total response rate of TCM symptoms in the observation group was 97.56% （40/41）， which was higher than that （87.80%， 36/41） in the control group （χ²=5.205， P<0.05）. After treatment， both groups showed declines （P<0.05） in systolic blood pressure （SBD）， diastolic blood pressure （DBP）， triglyceride （TG）， total cholesterol （TC）， low density lipoprotein cholesterol （LDL-C）， fasting blood glucose， 2-hour postprandial blood glucose （2 h PG）， glycosylated hemoglobin （HbA1c）， fasting insulin （FINS）， Homeostatic Model Assessment for Insulin Resistance （HOMA-IR）， body mass index （BMI）， waist circumference （WC）， waist-to-hip ratio （WHR）， leptin （LEP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， endothelin-1 （ET-1）， and inducible nitric oxide synthase （iNOS）. Moreover， the declines in the observation group were more obvious than those in the control group （P<0.05， P<0.01）. After treatment， both groups showed elevated levels of high density lipoprotein cholesterol （HDL-C）， adiponectin （ADP）， nitric oxide （NO）， and endothelial nitric oxide synthase （eNOS） （P<0.05）， and the above indexes in the observation group were higher than those in the control group （P<0.01）. ConclusionUnder the guidance of the thought of treating disease before its onset， modified Huanglian Wendantang was used to treat patients with metabolic syndrome. The decoction improved the clinical efficacy by ameliorating IR to improve insulin sensitivity， reducing inflammation， and protecting the vascular endothelial function. It inhibits cardiovascular risk factors without inducing adverse reactions， being worthy of clinical application and promotion.

Objective: To understand the status and related factors of knowledge, attitude and practice (KAP) on vision health among young children s parents in Bao an District, Shenzhen, so as to provide reference for further controlling myopia and promoting children s visual health. Methods: From May 16th to 26th, 2024, a stratified cluster random sampling method was used to conduct an online questionnaire survey on 7 666 parents of kindergarten children across 41 kindergartens in a street of Bao an District, Shenzhen. The t-test, variance analysis and multiple linear regression analysis were used to analyze the related factors of KAP on vision health among children s parents. Results: The pass rates of parental vision KAP and overall assessment were 25.10%, 98.49 %, 71.18% and 58.26%, respectively. The results of the multiple linear regression analysis showed that only fathers with myopia, only mothers with myopia, both parents with myopia, children in the bottom classes, middle classes, senior classes, and pre school had higher standardized scores for KAP on vision health among parents ( β=0.08, 0.11, 0.16, 0.17, 0.16, 0.16, 0.05, P <0.05), compared to both parents without myopia and children in daycare classes. Parents of young children with myopia, and who didn t know their children s visual acuity and their own visual acuity had a lower KAP standardized scores ( β=-0.02, -0.04, -0.05 , P< 0.05). Conclusions Young children s parents in Bao an District hold a positive attitude towards vision health, but are lack of knowledge and practice. It is imperative to transmit accurate information and concepts about children s vision health to parents in a targeted manner. In particular, knowledge and guidance should be strengthened for children s parents.

To understand the progress of, summarize the lessons learned from and analyze the challenges in the national schistosomiasis elimination program of China in 2024, this article presented the endemic situation of schistosomiasis and national schistosomiasis surveillance results in the People’s Republic of China in 2024. By the end of 2024, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region continued to consolidate schistosomiasis elimination achievements, and 7 provinces of Jiangsu, Sichuan, Yunnan, Hubei, Hunan, Anhui and Jiangxi maintained the criteria of schistosomiasis transmission interruption. A total of 450 counties (cites, districts) were found to be endemic for schistosomiasis in China in 2024, including 26 061 endemic villages covering 73 630 500 residents at risk of infections. Among the 450 counties (cities, districts) endemic for schistosomiasis, 388 (86.22%) achieved the criteria of schistosomiasis elimination and 62 (13.78%) achieved the criteria of transmission interruption. In 2024, a total of 4 102 624 individuals received immunological tests for schistosomiasis in China, with 44 823 sero-positives identified (1.09% seroprevalence), and a total of 169 722 individuals received parasitological examinations, with 1 egg-positives detected. A total of 27 321 cases with advanced schistosomiasis were documented in China by the end of 2024. In 2024, a total of 575 686 bovines were raised in schistosomiasis-endemic villages of China, and 113 842 bovines received immunological tests, with 235 sero-positives detected (0.21% seroprevalence), while no egg-positives were identified among the 167 475 bovines receiving parasitological examinations. In 2024, snail survey was performed covering an area of 680 498.27 hm² in China, and 190 778.66 hm² snail habitats were identified, including 59.09 hm² emerging snail habitats and 704.23 hm² reemerging snail habitats. In 2024, a total of 19 665 schistosomiasis patients receiving chemotherapy with praziquantel in China, and expanded chemotherapy was given to humans at 571 722 person-times and to bovines at 306 740 herd-times. In addition, snail control with chemical treatment covered 117 111.37 hm² snail habitats across China in 2024, and the actual area of chemical treatment was 66 562.95 hm², while environmental improvements were performed in snail habitats covering an area of 1 374.26 hm². The national schistosomiasis surveillance results showed that the mean prevalence rates of Schistosoma japonicum infections were both 0 among humans and bovines in China in 2024, and no S. japonicum infection was detected in snails. These data demonstrated that the prevalence of schistosomiasis remained at a low level in China in 2024; however, the areas of snail habitats remained high and the number of fenced cattle showed a slight increase. To address these risks, it is imperative to maintain the integrated strategy with an emphasis on management of the source of S. japonicum infection and intensified snail control in high-risk areas, and to reinforce schistosomiasis surveillance and forecast and snail control in high-risk areas.

Objective: To investigate the indoor fine particulate matter (PM 2.5 ) pollution and its influencing factors in children s bedrooms using solid fuel, so as to provide evidence for effective strategy to reduce PM 2.5 pollution. Methods: From December 2019 to November 2020, 198 households (108 in the north, 90 in the south) from two pilots in the north(Jiamusi in Heilongjiang Province) and south of China (Mianyang in Sichuan Province) were selected, and status of solid fuels using were obtained through home visits, dynamic changes in PM 2.5 concentrations in children s bedrooms were monitored by using real time online instruments, and the influencing factors of PM 2.5 pollution were analyzed by using a mixed effects model. Results: During the monitoring period, the daily PM 2.5 concentrations in the northern and southern pilot were 78.33 (40.50, 154.80) and 38.54(26.20, 58.46) μg/m 3, respectively, exceeding standard rates of 44.57% and 33.22%. During the heating period, the daily PM 2.5 concentrations in the northern and southern pilot were 212.50(133.60,244.10) and 104.42(73.97, 134.90) μg/m 3, respectively, with over standard rates of 96.75% and 86.96%. The mixed effects model analysis results showed that children s bedroom PM 2.5 concentrations were associated with solid fuel usage duration, window opening time, room layout (shared entrance door between kitchen and bedroom), indoor smoking, indoor humidity, and solid fuel use in the bedroom ( β =0.19, -0.05, 1.20, 0.43, 0.02, 0.35, all P <0.05). Conclusion Solid fuel combustion significantly comtributes to PM 2.5 pollution in children s bedrooms, with more pronounced impacts observed in northern China compared to southern regions.

OBJECTIVE To study the improvement effects and mechanism of proanthocyanidins （PACs） on steroid-induced osteonecrosis of the femoral head （SONFH） in rabbits based on the receptor-interacting protein kinase 1 （RIPK1）/RIPK3/mixed lineage kinase domain-like protein （MLKL） signaling pathway. METHODS SONFH model in rabbits was induced by injecting Escherichia coli endotoxin+methylprednisolone. The successfully modeled rabbits were randomly divided into Model group （normal saline）， low-dose PACs group （PACs-L group， 11 mg/kg）， high-dose PACs group （PACs-H group， 22 mg/kg）， high-dose PACs+ RIPK1 activator （rRIPK1） group （PACs-H+rRIPK1 group， 22 mg/kg PACs+4 μg/kg rRIPK1）， along with a control group （normal saline）， with 6 rabbits in each group. Each administration group was given relevant medicine once a day intragastrically/via injection， for 4 consecutive weeks. After the last administration， the levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in rabbit serum were measured. The changes in the microstructure of rabbit femurs， including bone mineral density （BMD）， trabecular thickness （Tb.Th）， trabecular number （Tb.N）， and trabecular separation （Tb. Sp） were examined. The histopathological features of rabbit femoral tissues were observed， and the apoptotic status of cells within the rabbit femoral tissues was detected. The mRNA expressions of vascular endothelial growth factor （VEGF） and bone morphogenetic protein 2 （BMP2） in rabbit femoral tissues were determined. The expressions of RIPK1/RIPK3/MLKL signaling pathway-related proteins in femoral tissues were detected. RESULTS Compared with the Control group， serum contents of TNF-α and IL-6， Tb.Sp， empty bone cavity rate， cell apoptosis rate， phosphorylation levels of RIPK1， RIPK3 and MLKL in femoral tissue were significantly increased in the Model group （P＜0.05）. BMD， Tb.Th， Tb.N， as well as the mRNA expression of VEGF and BMP2， along with protein expression of caspase-8， in the femoral tissues were all decreased （P＜0.05）. The bone cells in the femoral tissue were unevenly distributed， and the trabeculae were arranged sparsely. Compared with the Model group， the aforementioned quantitative indicators （P＜0.05） and pathological changes in all dosage groups of PACs showed significant improvements. Compared with the PACs-H group， the aforementioned quantitative indicators （P＜0.05） and pathological changes in the PACs-H+rRIPK1 group showed significant reversal. CONCLUSIONS PACs can ameliorate SONFH in rabbits， and its mechanism of action may be related to the inhibition of the activation of the RIPK1/RIPK3/MLKL signaling pathway， suppression of apoptosis in femoral tissue cells， and promotion of angiogenesis.

Flood disasters frequently occur in schistosomiasis-endemic regions of China during the flood season, which causes a high risk of schistosomiasis transmission. Therefore, it is particularly crucial to control schistosomiasis transmission during the flood season. Based on field schistosomiasis control needs, this article proposes scientifical and operational countermeasures during three phases of pre-flood preparation, response to flood disasters, and post-flood management, and emphasizes multi-faceted interventions as responses to the risk of Oncomelania hupensis spread and schistosomiasis transmission caused by flood disasters, including information collection, risk assessment, material reserve, health education, Oncomelania hupensis control, cercariae elimination, personal protection, and preventive treatment, so as to provide insights into schistosomiasis prevention and control during the flood season.

Objective:To analyze the self-evaluation and training needs of standardized parents from pediatric nurses after participating in the standardized residency training of pediatrics, and to explore the feasibility of pediatric nurses as standardized parents and the methods of training and management.Methods:A self-made questionnaire was used to investigate the self-evaluation, the influencing factors, the needs of training content and training form of standardized parents of pediatric nurses. Data analysis was made by SPSS 24.0 statistical software.Results:A total of 37 questionnaires were collected from the standardized parents of nurses. Among them, 36 nurses (97.30%) thought they were very competent for the work of standardized parent; 36 ones (97.30%) thought the most satisfied with their own was responsibility and fairness; 26 ones (70.27%) thought the least satisfied with their own was performance ability; 23 ones (62.16%) thought that the assessment of non-professional diseases would affect their performance in the assessment process; 34 people (91.89%) had the highest demand for training in the contents and skills of consultation; 16 ones (43.24%) thought that "teaching" and "giving cases to doctors and standardized parents for assessment simulation exercise" were the better training methods. Nurses used their own time to participate in training and assessment, and were willing to participate in the certification assessment of standardized parents.Conclusions:In the training of standardized parents of pediatric nurses, it is need to strengthen the training of various abilities, further improve the training contents and forms, reasonably arrange the training and assessment time, and increase policy support to make the standardized parent management of nurses more standardized.

Objective:To investigate the application value of 0.9% sodium chloride injection for a balloon catheter in bedside Doppler ultrasound-guided percutaneous dilatational tracheostomy in critically ill patients.Methods:A randomized controlled study was conducted involving 54 critically ill patients who were scheduled for tracheostomy at the Intensive Care Medicine, Jilin Province People's Hospital, from September 2022 to April 2024. These patients were randomly divided into a conventional group ( n = 27) and an ultrasound group ( n = 27) using the random number table method. The conventional group underwent empirical extubation, while the ultrasound group received extubation guided by a balloon catheter filled with 0.9% sodium chloride injection under ultrasound guidance. The following parameters were observed in both groups: duration of operation, incidence of blood oxygen saturation < 90%, incidence of puncturing the endotracheal tube or balloon catheter, distance from extubation site to the incisors, dosage of propofol, length of incision, and amount of bleeding. Results:Both groups of patients successfully completed the procedure on the first attempt, with no significant complications such as extensive bleeding, vascular injury, thyroid damage, or pneumothorax. In the ultrasound group, the incidence of puncturing the endotracheal tube or balloon catheter, duration of operation, and dosage of propofol were 3.7% (1/27), (6.2 ± 1.4) minutes, and 40 (40, 40) mg, respectively, all of which were superior to those in the conventional group [48.1% (13/27), (9.8 ± 2.7) minutes, 80 (70, 80) mg, χ2 = 23.19, t = 6.11, Z = -6.29, all P < 0.05]. The incidence of hypoxemia in the ultrasound group was 0, which was significantly lower than that in the conventional group [29.6% (8/27), P < 0.05]. The distance from extubation site to the incisors in the ultrasound group was 18 (17, 18) cm, which was significantly different from 18 cm of the conventional group ( Z = -2.62, P < 0.05). There were no statistically significant differences in length of incision and amount of bleeding between the two groups ( P = 0.652, 0.878). Conclusion:Performing PDT under bedside Doppler ultrasound guidance with a 0.9% sodium chloride injection-filled balloon catheter in patients requiring mechanical ventilation can reduce procedure duration, lower the incidence of hypoxemia and puncturing of the endotracheal tube or balloon catheter, decrease the use of sedative medications, and enhance the accuracy and safety of the procedure.

Objective:To investigate the effect of comprehensive pulmonary rehabilitation therapy on pulmonary and mo-tor function in children after pneumonia. Method:Children with improved acute symptoms of community-acquired pneumonia who were hospitalized in PKUFH-Ningxia Women and Children's Hospital from September 2020 to January 2021 were selected and di-vided into experimental group(n=30)and control group(n=30)according to the treatment intention of pa-tients and parents.Comprehensive pulmonary rehabilitation therapy was provided to the patients in the experi-mental group.The pulmonary function and motor function of the two groups were assessed prior to interven-tion and 3 months after intervention.The forced vital capacity(FVC),forced expiratory volume in one sec-ond(FEV1)and the ratio of forced expiratory volume in one second to forced vital capacity(FEV1/FVC),Borg scores and 6min walking test(6MWT)results were recorded and statistically analyzed. Result:After intervention,FEV1/FVC in experimental group was significantly higher than control group(P＜0.05);the FVC,FEV1 and 6MWT of the experimental group were significantly higher than those before inter-vention(P＜0.05).There were significant differences in FVC,FEV1,Borg scores and 6MWT between the ex-perimental group and the control group before and after intervention(P＜0.05). Conclusion:Comprehensive pulmonary rehabilitation therapy is helpful to the recovery of pulmonary and mo-tor function in children after community-acquired pneumonia.
